- Abstract
- Argues that classification systems have an important role to play in knowledge organization in the new world electronic order. The natural language approach is not incompatible with the use of a classification system and classification has untapped potential as a multilingual switching language. Librarians must learn to present classification systems in a language understood by a general audience and promote them as general knowledge organization tools

- Abstract
- The 21st edition of the DDC will be published in summer 1996, 120 years after the publication of the first ed. This paper describes the major changes in ed. 21 and explores some of the social, cultural, political, disciplinay, and knowledge organization forces behind the changes. The print version of ed. 21 is one manifestation of a larger underlying database that has also responded to several forces to meet present and future needs. Developments in the database and future directions to meet new uses of the DDC are addressed

- Abstract
- The Dewey Decimal Classification is preparing for the future in a number of ways. Editorial work is supported by a UNIX-based system and access to online bibliographic databases. Two editions of Electronic Dewey have been published and a Windows version is under development The Classification is continuously revised to keep pace with knowledge. Various changes have been introduced to address classifier convenience, modern classification design principles, and electronic distribution. A Dewey research agenda has been identified to guide future development and explore new opportunities. I will describe a few of the changes underway and suggest some questions to guide future directions for the Dewey Decimal Classification.

- Abstract
- This paper explores the history, uses cases, and future plans associated with availability of the Dewey Decimal Classification (DDC) system as linked data. Parts of the Dewey Decimal Classification (DDC) system have been available as linked data since 2009. Initial efforts included the DDC Summaries (the top three levels of the DDC) in eleven languages exposed as linked data in dewey.info. In 2010, the content of dewey.info was further extended by the addition of assignable numbers and captions from the Abridged Edition 14 data files in English, Italian, and Vietnamese. During 2012, we will add assignable numbers and captions from the latest full edition database, DDC 23. In addition to the "old friends" of different Dewey language versions, institutions such as the British Library and Deutsche Nationalbibliothek have made use of Dewey linked data in bibliographic records and authority files, and AGROVOC has linked to our data at a general level. We expect to extend our linked data network shortly to "new acquaintances" such as GeoNames, ISO 639-3 language codes, and Mathematics Subject Classification. In particular, we will examine the linking process to GeoNames as an example of cross-domain vocabulary alignment. In addition to linking plans, we report on use cases that facilitate machine-assisted categorization and support discovery in the Semantic Web environment.

- Abstract
- The Functional Requirements for Subject Authority Data (FRSAD) conceptual model identifies entities, attributes and relationships as they relate to subject authority data. FRSAD includes two main entities, thema (any entity used as a subject of a work) and nomen (any sign or sequence of signs that a thema is known by, referred to, or addressed as). In a given controlled vocabulary and within a domain, a nomen is the appellation of only one thema. The authors consider the question, can the FRSAD conceptual model be extended beyond controlled vocabularies (its original focus) to model classification data? Models that are developed based on the structures and functions of controlled vocabularies (such as thesauri and subject heading systems) often need to be adjusted or extended to accommodate classification systems that have been developed with different focused functions, structures and fundamental theories. The Dewey Decimal Classification (DDC) system is used as a case study to test applicability of the FRSAD model for classification data, and as a springboard for a general discussion of issues related to the use of FRSAD for the representation of classification data.

- Abstract
- Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22) will be issued simultaneously in print and web versions in July 2003. The new edition is the first full print update to the Dewey Decimal Classification system in seven years-it includes several significant updates and many new numbers and topics. DDC 22 also features some fundamental structural changes that have been introduced with the goals of promoting classifier efficiency and improving the DDC for use in a variety of applications in the web environment. Most importantly, the content of the new edition has been shaped by the needs and recommendations of Dewey users around the world. The worldwide user community has an important role in shaping the future of the DDC.

- Abstract
- This article reports on the second part of an initiative of the authors on researching classification systems with the conceptual model defined by the Functional Requirements for Subject Authority Data (FRSAD) final report. In an earlier study, the authors explored whether the FRSAD conceptual model could be extended beyond subject authority data to model classification data. The focus of the current study is to determine if classification data modeled using FRSAD can be used to solve real-world discovery problems in multicultural and multilingual contexts. The article discusses the relationships between entities (same type or different types) in the context of classification systems that involve multiple translations and/or multicultural implementations. Results of two case studies are presented in detail: (a) two instances of the Dewey Decimal Classification [DDC] (DDC 22 in English, and the Swedish-English mixed translation of DDC 22), and (b) Chinese Library Classification. The use cases of conceptual models in practice are also discussed.

- Abstract
- In 2003, OCLC published Dewey Decimal Classification and Relative Index, Edition 22 (DDC 22), in print and Web versions. The changes and updates in the new edition reflect a modern view of knowledge structures and address the general needs of Dewey users. The content of DDC 22 has been shaped by a number of social, geopolitical, and technical trends. The World Wide Web has provided a vehicle for more frequent distribution of updates to the DDC, and a medium for direct communication with Dewey users around the world. In addition to updating the system itself, other strategies are needed to accommodate the needs of the global Dewey user community. Translation of the system is one approach; another is mapping. Mapping terminology to the DDC is a strategy for supporting effective local implementation of the system while maintaining the internal cohesiveness of the DDC. This paper explores the usefulness of mapping terminology from English-language general subject headings lists produced outside the U.S.

- Abstract
- The Dewey Decimal Classification (DDC) system is a general knowledge organization tool used worldwide. The system features well-defined categories, well-developed hierarchies, meaningful notation, and a rich network of relationships. The nature of relationships in the DDC is richer than is apparent from a linear view of the system. The DDC accommodates the three basic thesaural relationships in the notational and structural hierarchy, through notes in the schedules, tables, and Manual; and in entries in the Relative Index. Derived relationships are shown through the synthesized notation, or through abridgment leading to broader classification. Options and translations provide alternative relationships. Additional relationships may be displayed through mapping of other thesauri.

- Abstract
- We describe a new information technology for knowledge organization: the development of a Web-accessible "taxonomy" server based on the top levels of the Dewey Decimal Classification (DDC) system. The server offers a publicly accessible automatic metadata creation tool that returns metadata encoded in XML. This paper discusses the role of the DDC in the project. Included in the metadata is automatic subject assignment based on the DDC and represented in XML. The project also provides a public browsing interface that uses the DDC as its underlying structure the DDC

- Abstract
- Options currently provided in the Dewey Decimal Classification system are reviewed. Options are an appropriate mechanism in a general purpose classification used by different kinds and sizes of libraries around the world. Dewey provides the universal option of close versus broad classification. Options also are provided to give emphasis to jurisdiction; racial, ethnic, or national group; language; topic; or other specific characteristics. Various devices are detailed or suggested to introduce options. Options may be an impediment to retrieval of information across systems. Options should not be introduced as a substitute for the appropriate placement of a topic in the Classification. Options help accommodate cultural differences in the Classification, and provide a mechanism for emphasizing topics of local importance.
